Energy Efficiency in Large Buildings

Improving building energy efficiency will help protect Denver’s quality of life and strengthen the economy. Investing an estimated $340 million in improving building energy efficiency could result in 4,000 local jobs and $1.3 billion in energy savings over 10 years. The energy used in large buildings results in 57 percent of Denver’s harmful greenhouse gas emissions.

Energy use was cut 4.5 percent by the 1,161 buildings reported in both 2016 and 2017. Those owners and tenants saved $13.5 million in 2017. Energize Denver aims to meet Denver’s 80x50 Climate Action Plan goals that buildings use 30% less energy by 2030, use 50% less energy by 2050, have 50% less thermal heating emissions by 2040, and that all new buildings are net-zero energy by 2035.
